Derail



S. W. HAYES DERAIL Filed July 21, 1922 t mo'y -:2 Jewel s kn i, STAN, Sta i county 0 have invent-er proyeinents Tn derails a modern oractice, tltion of the derailin member Pi; considerable extent specially the sliding type and the entire mei'nber ise single and necer The production of s 's difficulties si inequehties in strains in the castin a different rate fioin these places of initial one being danger points may give Way under the ended strains in cident to use.

This diiliculty would be increuser or quite to the point of impossihil the attempt made to use inang". Which is diflicult to cast and hot. in s'niple form This invention overcomes by making the derail blocl: or not, separate from the be railing member, and mounti N hody of the deraning Jer in any able Way, preferably by detael at the junction of the t ino' body and the longituo derail block.

The vention further provides for making the derail block and the derailine of metal of diiferen character,

made in accord body guidi,

the sort disclosed in my prior patent No.

1 9 T M 1,00 $6}, of oune ll, 1919. In the illustrated derail the side Wall 1 of the base is con- :d by the forward cross Wall 2, the roof Winner 3 and the rear wall t, the other side ll not being shown This base furnishes orward and rear bearings indicated respecrively at and 6, the upper lug 7 being also egarded as a part of ierailing member con'iprises a derail block rope; 8, and a supporting body 9 therefor guided by the which is contained in ano base. The forward bearings are constituted the form illustrated of studs 10 extending outward from opposite sides at the forward end of the body, and slidable on the fori'vzzrd bearing grooves The rear hearing cons sts of a central upstandinp hool;

mounted slidably in and he- 1 4 k shaped 11b 1i 1e rear tween tl bearing lugs The derail hlocl' 8 separately made and firmly d ed to the body of the derailing meioher eferably by a Joint in the nature of mortise and tenon Which take various V rms one of which is that illustrated is evident however, that quite different mountings may be employed, and it will be observed that the derailing member is T'- shan d, its body 9 constituting the stem of the and its derail block 8 the cross bar, and that the joint is located at the intersection of? the stem and cross bar portions. In the drawings, the body 9 of the derailing in einber has a substantially upright forward shoulder portioi'i f a socket parts of Whose inner walls 13 are designed for contact with the corresponding faces 14 of a tenon part 15 projecting from the bottom of the derail block 8, thus constituting an upwardly opening vertically socketed joint. This mortise and tenon or socket joint irrespective of bolts or other securing means furnishes ample bearing surface to take the thrust in all directions. I prefer to provide the rear bearing. The

the derail block at its front side with a depending flange 16, the inner face of which is adapted to contact with the outer oi the corresponding part or the body of the derail and which assists in resisting strain. The underside l7 oi? the derail bloc formed to make a proper bearing on the upper surface of the upright portion '5 2 oi the body of the derailing member. This bearing is preferably located at a level which is sub tantially that of the rail tread, when the derail is open, or to speak more exactly, which isadjacent to the top of the corner of the rail head.

A pair of bolts 18, passed through registering holes 20 and 21 in the body and block respectively and with their heads seated in square countersinks 22 serves to secure the parts in assembledrelation and to resist spreading of the socket under strain, but permit the removal of the derail block when desired. It will be understood that the derail block may be of any suitable contour, for derailing in either or both directions, the block shown being provided with a hand hole 23 for operating the derail by hand when desired.

It may be noted in conclusion that the upwardly opening mortise and tenon joint between the derail block and the body of the derailing member is particularly eiiicacious in respect to maintaining its integrity under the unusually severe strains to which derailing members are subjected and against which they must be proof, the practicability of a derailingmember composed of separate- 1y made parts being conditioned on the strength of the joint between such parts and the character and locationof the joint be ing thus vitally important. By locating the upwardly opening mortise and. tenon joint at the widest part 01: the body, so that the joint itself is wider than the body except at that, part, the quality of? dependability esscn'tial to a derailing member is enhanced and this characteristic further assured. by

the spread-preventing action of the boltsas respects the mortise or socket.
